Study Notes

Fire Hose Maintenance and Care

Fire hoses exposed to oil should be washed with mild soap or detergent.
Mechanical damage prevention includes clearing broken glass before deploying hoses.
Regular repacking of unused hose loads helps prevent age deterioration.
To avoid thermal damage, hose should not be laid on hot pavement to dry.
Woven-jacket fire hose requires brushing to clear dust and dirt after use.

Hose Rolling Techniques

The twin donut roll is compact and ideal for high-rise incidents.
A straight roll of hose leaves one coupling exposed for easy access.
The accordion load positions hose on its edge, laying next to each other.
The minuteman load allows the hose to be carried on the shoulder, minimizing obstacles.

Hose Types and Functions

Hard suction hoses are used for drafting from static water sources.
Supply hoses transport water from hydrants to pumping apparatus.
Attack hoses carry water from the pumping apparatus to the fire nozzle.
Large diameter soft sleeve hoses connect pumps to pressurized water sources.

Inspection and Testing

Fire hoses should be service tested every year, and within 90 days of first use.
Hoses stored in the fire apparatus bay require more frequent inspection due to exposure to pollutants.
Hoses should be inspected for damage to the hose jacket and threads before storage or reuse.

Couplings and Connections

Hose couplings connect sections together to form a long hoseline.
Male couplings have exterior threads, while two-way couplings do not have male or female threads.
Lugs on fire hose couplings assist in tightening and loosening connections.
Recessed lugs on booster hose couplings require special wrenches for adjustment.

Loading and Storing Hose

Hoses should be loaded loose enough in the hose bed to fit a gloved hand between folds.
Large diameter hoses are ideally loaded in a flat configuration.
A combination load allows for both forward and reverse lays from a split hose bed.
To prevent damage when drying, secure couplings to the rack or tower.

Environmental Considerations

Hose exposure to gasoline can rapidly separate the inner lining.
Natural fiber hoses are susceptible to mold and mildew if stored wet.
In cold conditions, allowing some water to flow through the nozzle prevents freezing.

Summary of Hose Management Practices

Regular cleaning and inspection are crucial for maintaining fire hoses.
Various rolling techniques are suited for different situations and ease of transport.
Proper loading techniques can enhance operational efficiency while reducing wear and tear.
Understanding hose types, their functions, and coupling characteristics aids in effective firefighting operations.
